Application filed April 5, 1916. Serial No. 89,039.

To all whom it may concern:

Be it known that I, JAMES W. Fnnmm, a citizen of the United States.'anda resident of Buhl, in the county of Twin Falls and State of Idaho, haveinvented a new and Improved Clover-Huller, of which the following is afull, clear, and exact description.

My invention relates to clover hullers involving a cylinder and aconcave, and has for an ob]ect to provide a constructlon that may becheaply produced for the most part from elements and materials readilyavailable.

The invention also has for an object to provide a clover huller improvedin various particulars with a view to promote strength and efliciency,efiectiveness in operation, and convenience in the adjustment of theparts.

The invention will be particularly explained in the specific descriptionfollowing.

Reference is to be had to the accompanying drawings forming part of thisspecification in which similar reference characters indicatecorresponding parts in all the views.

Figure 1 is an end elevation ofva clover huller embodying my invention;Fig. 2 is a sectional plan view; Fig. 3 is a longitudinal verticalsection; and Fig. 4 is a transverse vertical section.

My improved clover huller includes a suitable frame 10, mounted in whichis a cylinder, designated generally by the numeral 11, the constructionof which cylinder will be more particularly eXplained hereinafter. Thecylinder is secured to a shaft 12 turn-' ing in bearings 13 on the frame10 and driven in any suitable manner as by a belt (not shown), runningover a pulley 1%. A housing or casing 14: is provided with hinged covers15 at the top to afford access to the interior, and at the bottom, thecasing is provided with a discharge spout 16.

A concave, designated generally by the numeral 17, is provided. At theupper end the concave 17 is supported on a bar 18 resting on the end.members of the frame 10.

The concave is formed of sheet metal which is bent downwardly at itslower end as at 19 to rest on a transverse rod 20. The bar" inder 11into which the clover is delivered by a spout 2 1.

In order to produce a'strong and cheap cylinder, I form the same from apulley 25 having a hub 25 secured on the shaft 12 and I face said pulleywith-rasp sections 25*, whichmay be formed in rings or sectors.Similarly, the sheet metal concave 17 is faced with rasp sections 17 Theresult is a very effective cylinder and concave, and also, the facing ofthe cylinder may be renewed without discarding the pulley and thecylinder thus maintained in proper condition at little cost.

In order to adjust the concave at its upper end and to release the samefor the removal of stone or other foreign matter, I provide on the bar18, threaded studs 26 which extend through brackets 27 suitably boltedto the frame 10. The said studs are provided with set nuts 28 atopposite sides of said brackets. 7

To provide for adjusting the lower end of the concave 17, the supportingrod 20 thereof, is carried in blocks 29 slidable vertically in boxings30 and provided with studs 31 having set nuts 32 to adjust the height ofthe said blocks.

Having thus described my invention I claim as new, and desire to secureby Letters Patent: v

'1. A clover huller including a housing having a discharge outlet at thebottom, a cylinder mounted to turn in the housing, a concave, saidconcave being formed of sheet metal and having its lower end turneddownwardly at the said discharge outlet, a transverse rod supporting thesaid lower end of the concave, an adjustable transverse bar on which theconcave rests at its upper end means for adjusting said transverse rodto and from the cylinder, means for adjusting said transverse bar to andfrom the cylinder,

the transverse bar having a depression presentinga transversely concavedsurface and 'the' concave belng correspondingly curved presenting aninlet throat, and means to deliver material to said throat.

2. A clover huller including a cylinder, a concave formed of sheet metaland having its lower end bent downwardly, a transverse rod supportingthe said downturned end, a

transverse bar, means for adjusting said bar to and from the cylinder,the said bar having a depress on transversely curved, and

the concave being correspondingly curved and presenting an inlet throatbetween said curved portion and the cylinder, and means to delivermaterial to said throat.

3. A clover huller including a cylinder, a concave formed of sheet metaland having its lower end bent downwardly, a transverse rod supportingthe said downturned end, a transverse bar, means for adjusting said barto and from the cylinder, the said bar having a depression transverselycurved, a plate secured to the said bar and having a depression curvedto correspond with the depression in the bar, the concave beingcorrespondingly curved and presenting an inlet throat between saidcurved portion and the cylinder, and means to deliver material to saidthroat.

4. A clover huller incliiding a cylinder, a concave, means to supportthe lower end of the concave, a transverse bar supporting the upper endof the concave, and formed with a depression concaved transversely, thesaid concave having a depression curved to correspond with thedepression of the said supporting bar, and rasp sections on the face ofthe concave, said rasp sections at the depressed portion of the concavebeing formed tocorrespond with said depression.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
